Across four sessions between Wednesday, April 10 and Saturday, April 13, the Sydney Opera House will come to life with the sights and sounds of the Ministry of Magic, 12 Grimmauld Place and the return of He-Who-Must-Not-Be-Named, because JK Rowling's boy-who-lived and his pals are never far away from a theatre — or a concert hall. And tickets are now on sale.

This time around, viewers can expect something a little different. While the event will run as usual, it's the score itself that'll stand out. After doing the honours on the first three HP flicks, veteran composer John Williams stood aside, with two-time Oscar nominee Patrick Doyle (Hamlet, Sense and Sensibility) in charge of the fourth, and Nicholas Hooper whipping up wondrous wizarding soundtracks for the final three.
